The Lowdown
Alright, Rusty here, let's see what's shaking.
For the next few days, there’s nothing doing. We’re in a quiet spell until Friday morning the 21st. Then the surf starts waking up. The best run will be from Sunday the 23rd through Wednesday the 26th.
Jaconé is the spot. It’s a consistent, exposed break that handles swell well. Friday morning the 21st brings a clean 6ft swell from the ENE, period around 8 seconds, with light offshore NNE winds. The combined energy is moderate at 454 – there’s some punch. Good for intermediates.
Saturday morning the 22nd is a no-go with onshore SW winds. Skip it. Sunday morning the 23rd is the first real winner: clean 5ft swell from the SSW, 10-second period, and a light cross-off breeze from the ENE. Combined energy is 501. Water temp is about average for the time of year. Expect very good, clean waves. This is a top call.
Monday the 24th the swell builds to 7ft from the S, period stretching to 13 seconds – that’s proper groundswell. Combined energy is strong at 1596. Light rain and cross-off winds keep it clean, but it’s getting into expert territory. Tuesday morning the 25th hits a peak at 10ft from the S with a 14-second period and a combined energy of 3224 – that’s very strong. Cross-off wind, but it’s too big for this break. Only for experienced surfers.
Wednesday morning the 26th is the standout: 7ft S swell, 13-second period, combined energy of 1499. Light NE offshore winds will give you glassy, clean waves. The forecast says excellent conditions for experienced surfers. Crowds are possible here, but the quality will be worth it.
After that, it drops off. Thursday the 27th and Friday the 28th still offer clean, smaller waves from 4ft to 6ft with good period, but the energy is lower. The best of that run is Friday morning the 28th: 4ft S swell, 13-second period, light offshore NE winds, combined energy of 623 – very good, clean, but mellow.
Saturday the 29th has a quick spike of 7ft from the ENE with an 8-second period and combined energy of 702, but it’s short-period windswell, not the same quality. From Sunday the 30th onward, it fades into small, weak, and ordinary surf for several days. A couple of poor, onshore days hit on Tuesday the 1st and Wednesday the 2nd of September, so you’ll be on the beach.
The one to lock in is Wednesday morning the 26th of August – that’s the best session of the whole outlook. Clean, powerful groundswell with offshore winds, and a size that will get your heart pumping.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
